Senior Citizen Act Verdict against Father's will

My brother residing in US filed case with district court along with my mother for ill treatment and non-maintenance of my mother. The history is my late father willed the property to myself, mother and my brother equally (1/3rd each). However since the death of my father he wanted to sell the house and take the money to US (along with my mother). Because of this I had some verbal fights/abuses with my mother which are on record (voice recordings). Thus the district court using Senior Citizen Act law ruled in the favor of my mother citing those recordings and didn't listened to my side of the story. Also the court has given the complete ownership to my mother and verdict to evict the property. The court didn't consider father's will as my mother told that this is self build property by my father and her and she has the claim to this property after father's death. Can district court give the absolute ownership to my mother and void my father's will ? If not where can I challenge this ?
